Microwave premelting and full melting process for glass batch materials and equipment thereof

Abstract

The invention relates to a microwave premelting and full-melting process for glass batch materials and equipment thereof. The process is characterized in that the glass batch materials are put into avertical matching bin, and microwave heating devices are arranged around the outer side wall of the vertical matching bin. The microwave heating devices gradually heat the glass batch materials from top to bottom to enable the glass batch materials to automatically flow out from the bottom of the vertical matching bin under the action of gravity after completing dehydration, drying, chemical thermal decomposition, solid phase sintering and semi-melting and then fall into various glass melting equipment below the microwave heating devices, further heats and melts the the glass batch materials by adopting microwaves, flames or electrodes so as to finally complete the melting, clarifying, homogenizing and cooling procedures in the glass melting process, and then sends the glass batch materials to a glass forming procedure for forming glass products; a hot gas generated in the heating process is discharged from the upper port of the vertical matching bin, and the cold glass batch materialat the upper part of the bin is heated in the process.

Description

technical field [0001] Melting glass melting process and its equipment, especially the microwave melting glass melting process and its equipment. Background technique [0002] At present, the traditional glass melting method is to heat the surface of the flame or to heat the molten glass with electrodes. Among them, the problems of flame surface heating are: 1. The thermal efficiency is very low and the energy loss is serious. 2. A large amount of greenhouse gases and some harmful gases are emitted. 3. The structure of the furnace is complicated, the construction period is long, and the investment is large. 4. The melting cycle is long. , the temperature is high, 5, the fine powder with a small particle size, which accounts for about 30% of the total glass raw materials, cannot be used, which not only causes resource loss but also greatly pollutes the environment. The disadvantages of electrode energization heating are: 1. The electrode is easy to wear and tear, and the ser...
